Culling Using Masked Depths

摘要

A simple technique for zmax-culling on a per-tile basis conservatively estimates the maximum depth of the samples in a tile using a layer of masks and a number of zmax-values. No feedback loop is needed from the depth unit, in some embodiments. In addition, the occlusion test may be masked.
